The biggest issue is the $20k+ price and their use of a basic, modified Swiss movement. For that amount of money you should be getting the (great) design and an in-house movement. Just my opinion though.

There are a lot $20k+, even $50k+ ETA 2824-2 watches. In most cases while the base movement is the same, the attention to detail for the movement is what separates a < $1,000 Hamilton from a > $80k Christiaan van der Klaauw. In this case, the base movement is a spectacular workhorse that can meet COSC that allows for the innovation that sits on top of it. If it had an in house movement (which isn't necessarily better, and I can think of several that aren't as good as a 2824-2) then the price would go up accordingly.

The Ressence is based on the ubiquitous ETA 2824-2, but it's modified extremely heavily. The 2824-2 is not inherently a regulator movement, they fitted magnets onto the gear trains to carry the various subdials as the time progresses. Ressence also completely removed the winding stem/crown, and you set the time by rotating the caseback (at least in the case of the Type 3 and onwards, as far as I know).

I think this is an example of a watch that punches above its base movement, the technology that lives in the watch are what justify its price in my eyes.
